Committing to one color, such as Diana Vreeland and her beloved red (image 2 and honored in image 9), comes more easily if you have a steadfast favorite. However, even if you don't like the idea of using so much of one color, seeing it in practice does help emphasize the power of thoughtful color and mixed textures and patterns.
That mixture is the key to a good-looking monochromatic room. In the first image, the slick lacquered walls are complemented by a cozier velvet couch and a supple leather chair in a very close blue. Similarly, the white room in image 3 pairs a shiny, bright white coffee table with a nubby, slightly more ivory rug. In the very red image 5, the patterns and texture vary between the rug, pillows, and upholstery.
